Using Liquibase with MariaDB, skySQL, or MariaDB AWS RDS

MariaDB delivers operational agility with key enterprise features, including real ACID compliance and full SQL. It provides two solutions:

  • MariaDB Platform, which includes an open-source database solution—MariaDB Server along with Xpand, ColumnStore, and MaxScale.
  • MariaDB Cloud (or MariaDB SkySQL), which is a cloud database service (DBaaS) that delivers MariaDB Platform on the expert-maintained cloud infrastructure from MariaDB Corporation.

You can also use MariaDB on Amazon RDS. For more information about MariaDB, see the MariaDB Knowledge Base.

Supported Versions

  • 10.2
  • 10.3
  • 10.4
  • 10.5
  • 10.6
  • 10.7

Note: Supported versions tested with Liquibase Test Harness.

Prerequisites

Warning: If you create the Liquibase properties file, do not name it mariadb.properties. This file name conflicts with a properties file that is released with the MariaDB driver.

Install Drivers

To use Liquibase and MariaDB, you need to have the JDBC driver .jar file.

Liquibase comes with a pre-installed driver for this database in the liquibase/internal/lib directory. For more information, see Adding and Updating Liquibase Drivers.

If you use Maven, you also need to download the driver JAR file and configure your Maven pom.xml file to use the local copy of the driver. For more information, see Configuring Liquibase Attributes in your Maven POM File. For example:

<dependency>
    <groupId>org.mariadb.jdbc</groupId>
    <artifactId>mariadb-java-client</artifactId>
    <version>3.0.4</version>
</dependency>

Test Your Connection

For Liquibase and MariaDB to work, you need to:

  1. Ensure your MariaDB is configured. See the following:
  1. Specify the database URL in the Liquibase properties file or as a parameter to the command in the CLI. See the following:
  1. Create a text file called changelog (.xml, .sql, .json, or .yaml) in your project directory and add a changeset.
  1. Navigate to your project folder in the CLI and run the Liquibase status command to see whether the connection is successful. You can pass arguments in the CLI or keep them in the Liquibase properties file.
  2. liquibase --username=test --password=test --changelog-file=<changelog.xml> status
  3. Inspect the SQL with the update-sql command. Then make changes to your database with the update command.
  4. liquibase --changelog-file=<changelog.xml> update-sql
    liquibase --changelog-file=<changelog.xml> update

From a database UI tool, ensure that your database contains the table you added along with the DATABASECHANGELOG table and DATABASECHANGELOGLOCK table.

MariaDB Server

  • Check the status of the database by running the SHOW [GLOBAL | SESSION] STATUS command.
  • Specify the database URL in the Liquibase properties file, as follows:
  • url: jdbc:mariadb://<host>:<port>/<dbname>

MariaDB on AWS RDS

  • Check the connection by using the mysql utility and running the following:
  • mysql -h <endpoint> -P 3306 -u <mymasteruser> -p

    Note: The alternative way is to connect with the SSL certificate.

    You can find the connection information in the AWS Management Console:

    1. Open the Amazon RDS console
    2. Select Databases and choose the needed database
    3. Select Connectivity & security. You will see all information under Endpoint & Port.

    To find the connection information using the AWS CLI and RDS API, refer to the Connecting to a DB instance running the MariaDB database engine documentation.

  • Specify the database URL in the Liquibase properties file, as follows:
  • url: jdbc:mariadb://<endpoint>:<port>/<dbname>

    Example: url:jdbc:mariadb://myrds.cz1j1vh9uvuo.us-east-1.rds.amazonaws.com:3306/mydatabase
